longines watch spares or repair

Hi,selling my longines quartz watch,for spares or repair,the watch works but the winder has come out,as you can see in the picture,do not know how to put it back.The glass has a couple of small scratches on it,and the strap is a bit tatty.It measures 32mm across,it is gold plated,with steel es with box and papers,but the hinge on the box is also a bit tatty,as you can also see in the picture.Any questions please email me.
